#stove-installLICENSE- Credential
- No solid-fuel-named class — nearest captures: C-1f 'Heating, cooling and circulating air' (NAC 624.190(f): 'The fabrication and installation of systems for the heating, evaporative cooling and circulation of air') for the appliance-as-heating-system; C-1e (NAC 624.190(e)) and C-13 Sheet Metal (NAC 624.300 — CITE CORRECTED from 624.270/.280) both name 'patented chimneys, flues' for the venting; C-18 Masonry (NAC 624.350) for masonry fireplaces. If the work is heating-type, the NRS 624.031(6) under-$1,000 exemption is VOID — licensed from $0; otherwise $1,000. NRS 624.970 (added 2023; residential-improvement contract elements + permit duties) and NAC 624.013 ('repair' includes replacement/routine maintenance of mechanical equipment 'including... chimneys'). EPA AXIS — COUNTY-LEVEL OREGON PATTERN: Washoe County District Board of Health Reg 040.051 (revised 5/26/2016, as filed in the EPA SIP docket): 'Only EPA-certified wood heaters shall be installed on any residential or commercial property located within the Health District' and on transfer/conveyance each uncertified wood heater 'shall be removed or replaced' before escrow/title change ('Rendering a device inoperable is not acceptable in lieu of removal'); current district text not re-read (NNPH site unreachable), July's 'notarized Notice of Exemption' detail not re-verified; no Clark County equivalent found.

Chimney flashing: is a credential required in Nevada?
#chimney-flashingLICENSE- Credential
- C-15 Roofing and Siding — C-15a Roofing (NAC 624.320): 'installation, application, alteration and repair of watertight and weatherproof material used on roofs', e.g. asphalt, pitch, tar, felt, shakes, shingles, tile, slate, photovoltaic roof tiles (+ C-15d Waterproofing per July). Flashing itself is verbatim-named in the SHEET METAL scopes instead: C-13 (NAC 624.300 — CITE CORRECTED from 624.270/.280) and C-1e (NAC 624.190(e)) both cover 'cornices, flashings, gutters... patented chimneys, flues and metal roof systems' — so NV chimney flashing has two lawful classification lanes (C-15a roof-surface work; C-13/C-1e sheet-metal work), plus C-18 masonry (NAC 624.350) for the chimney structure. $1,000 repair exemption (NRS 624.031(6); flashing repair is arguably not plumbing/heating-type, so the exemption survives below $1,000 unless a permit is required); NAC 624.013 folds chimney replacement/maintenance into NRS 624.970 'repair' duties

Gas log installation: is a credential required in Nevada?
#gas-log-installLICENSE- Credential
- LP lane tracked separately: a propane log-set install needs BOTH the NSCB C-38b (or C-1) classification AND LP Gas Board licensure (NRS 590.535 — installing LPG appliances is a licensed business; class 3A = vapor piping and appliances) with a technician certificate of competency (types per the Board; July names 'APPLIANCE'/'INSTALL' not re-verified) — the only dual-board gas-log lane in the West batch; NG log sets need only the NSCB class

Before anyone goes on your roof
What should you ask a chimney company in Nevada?
- Is your company a member of the National Chimney Sweep Guild (NCSG)?
- Does the technician coming to my home hold an individual NCSG certification, and which one?
- Does the technician hold a National Fireplace Institute (NFI) certification — and for which fuel: wood, gas, or pellet?
- What other certifications does the technician hold (for example, CSIA), and can I check them on the issuer's own roster?
- What state or local license or registration covers this work here, and what is the number?
- Will you send a certificate of insurance, dated and naming your company, before work starts?
- Which NFPA 211 inspection level — Level 1, 2, or 3 — are you performing, and why that level?
- Will you show me what you found — photos or video of the flue — in writing?
We take no fee from any certification body, guild, or contractor, and are not paid to mention anyone named.
